  \begin{theorem}
    There is no largest prime number.
    \begin{equation}
      \label{eqn:LBmodel}
      C_{L}=C_{L0}+C_{L\alpha }\left ( \frac{1+\sqrt{X}}{2} \right )\alpha 
    \end{equation}
  \end{theorem}

  \begin{proof}
  \begin{enumerate}
    \item<1-| alert@1> Suppose $p$ were the largest prime number.
    \item<2-> Let $q$ be the product of the first $p$ numbers.
    \item<3-> Then $q+1$ is not divisible by any of them.
    \item<1-> But $q + 1$ is greater than $1$, thus divisible by some prime number not in the first $p$ numbers.\qedhere
    \end{enumerate}
  \end{proof}
